1. A chemical process comprising:
a. a first reaction in which a halogenated carbonyl of iron is a reactant;
b. a second reaction in which a reactant of the general formula Y—CCl3 reacts with an alkene in a reactor thereby producing a halogenated hydrocarbon;
c. wherein the second reaction occurs at a time selected from during the first reaction and after the first reaction;
d. wherein carbon monoxide is a product of the first reaction;
e. wherein the reactant of the general formula Y—CCl3 is added to the reactor during the second reaction;
f. wherein Y is selected from hydrogen, halogen, alkyl group, nitrile, and carboxylate; and
g. wherein a compound selected from an Fe(II) complex and an Fe(III) complex is removed from the reactor, subjected to separation, and returned to the reactor.
